Side 2 - BBOWN, of the said district, hath deposited in this office the title of a book, the right whereof he claims as author, in the words following, to wit : " Sertorius : or, the Roman Patriot.
Side 51 - Also, as a cubic foot of water weighs just 1000 ounces avoirdupois5 the numbers in the table express, not only the specific gravities of the several bodies, but also the weight of a cubic foot of each in avoirdupois ounces ; and hence, by proportion, the weight of any other quantity, or the quantity of any other weight, may be known, as in the following problems.
Side 98 - BY LOGARITHMS. RULE. From, the logarithm of the dividend subtract the logarithm of the divisor, and the number answering to the remainder will be the quotient required.
Side 37 - If the vessel be double-decked, take the length thereof from the fore part of the main stem, to the after part of the stern post, above the upper deck ; the breadth thereof at the broadest part above the main wales, half of which breadth shall be accounted the depth of such vessel...

Side 37 - ... ^three-fifths of the breadth, and take the depth from the under side of the deck plank to the ceiling in the hold, then multiply and divide as aforesaid, and the quotient shall be deemed the tonnage.
Side 15 - Multiplication is performed on this line, by extending from 1 to the multiplier ; that extent will reach from the multiplicand to the product. Suppose, for example, it were required to find the product of...
Side 16 - Sic. is found by extending from 1 to the breadth ; that extent will reach from the depth to a fourth number, and the extent from 1 to that fourth number will reach from the length to the solid content.
Side 51 - To find the Magnitude of any Body, from its Weight. As the tabular specific gravity of the body, Is to its weight in avoirdupois dunces, So is one cubic foot, or 172U cubic inches, To its content in feet, or inches, respectively.
Side 88 - Add together the three sides ; from half their sum subtract each side, noting down the remainders ; multiply the half sum by one of those remainders, and that product by another remainder, and that product by the other remainder ; the square root of the last product will be the area.* EXAMPLE.
